PSI equips the Swiss Light Source SLS for the future
Green light for SLS 2.0: The planned upgrade of the Swiss Light Source SLS can proceed; the funding is provided for within the framework of the ERI Dispatch for 2021-2024, which has been approved.
Magnetic vortices come full circle
The first experimental observation of three-dimensional magnetic ‘vortex rings’ provides fundamental insight into intricate nanoscale structures inside bulk magnets, and offers fresh perspectives for magnetic devices.
Ruzicka Prize
The Ružička Prize 2020 goes to Dr. Patrick Hemberger (PSI) for his research on understanding the mechanisms of catalytic fast pyrolysis by unveiling reactive intermediates in heterogeneous catalysts.
World Record: 7 nm Resolution in Scanning Soft X-ray Microscopy
During the past decade, scientists have put high effort to achieve sub-10 nm resolution in X-ray microscopy. Recent developments in high-resolution lithography-based diffractive optics, combined with the extreme stability and precision of the PolLux and HERMES scanning X-ray microscopes, resulted now in a so far unreached resolution of seven nanometers in scanning soft X-ray microscopy. Utilizing this highly precise microscopy technique with the X-ray magnetic circular dichroism effect, dimensionality effects in an ensemble of interacting magnetic nanoparticles can be revealed.

COVID-19 - travel assistance websites launched
The Bio Nano spinout of Prof. Aeppli has launched new travel assistance websites that provide continually updated information on restrictions such as multi-day quarantines imposed on travel between countries, together with the latest pandemic predictions so that travellers can make informed decisions.
Harnessing components from the optical internet for programmable spectroscopy
A novel concept for extracting information from spectra where traditional post-processing procedures fail, dubbed ‘software-defined spectroscopy’, offers a fresh approach to high-resolution terahertz spectroscopy. The new method implements an ‘optical comb’ and combines it with a programmable modulator, all using components from the optical internet.
Two-color snapshots of ultrafast charge and spin dynamics
In a joint research effort, an international team of scientists lead by Emmanuelle Jal (Sorbonne Université) performed a time-resolved experiment at the FERMI free-electron laser to disclose the dynamic behavior of two magnetic element of a compount material in only one snapshot. The X-ray Optics and Applications group developed a dedicated optical element for this experiment that is usable with two different photon energies (colors) simultaneously.
